.BuildingSystems.Fluid.HeatExchangers.ConstantEffectiveness

Information

Model for a heat exchanger with constant effectiveness.

This model transfers heat in the amount of

Q = Q_max ε,

where ε is a constant effectiveness and Q_max is the maximum heat that can be transferred.

For a heat and moisture exchanger, use BuildingSystems.Fluid.MassExchangers.ConstantEffectiveness instead of this model.
